Also known as American Smoke Tree Burl, this wood is one of the rarest woods in North America. In my opinion, it's also one of the most beautiful. I obtained these blanks from Alabama and they have been air drying for a couple years. They vary in size, and are a little rough cut, but they are all at least 3/4"sq x 5" long. I also have a limited supply of pieces that are about 1"sq x 5"+. These are solid pieces but as with all burls, there could be some voids due to the wild growth pattern.
